force applied to a wheel F=ma rolling friction is F=-μR normal force R=-mg Is that right? going back to the Two-wheeled inverted pendulum that i have to find acceleration of, by using the point c that is the centre of mass of the whole vehicle, how do I go about finding the torque at that point, which is on a line that is displaced at exactly the center of the rod that is in the axis...

I'd say that the only net forces acting on a point C of a vehicle are torque (2h mg sin θ ) force that gives us acceleration of a vehicle (2h ma cos θ ) and torque of a point C that is τ=Iω Image: Sorry I've been trying to figure it out for days and I still have trouble with applying these forces in order to solve this problem, so I may have a flawed understanding of it right now. As I...

I think I can- but it's really not that simple when there's so many parts here to consider. It simply moves (accelerates uniformly with this unknown yet constant acceleration) in the right direction as the picture suggests. So it's not moving upwards/downwards- just rolling without slipping we assume here that this motion is in the right direction of this horizontal...

Okay so having all of these Drawn out, how can I find acceleration a that is at the point c which is centre of mass of a vehicle like this? @studiot, @Lizwi And am I Missing some important factors here? - θ is the angle that the pink/black rod moves from the equilibrium position that is on the normal line to the surface in order to accelerate a vehicle- something like a segway/...

Let's picture a Rolling without slipping Wheel, that constantly accelerates. radius of a wheel/circle is rr. Basically any wheel of a vehicle is rotating around its fixed axis - AoR -(axis of rotation) Most of the times wheels have this AoR perfectly in the center of the circle/wheel/cylinder. What I want to understand is how can we describe the torque of such a wheel? Because as I...

hey It's me again, I need Help with this pendulum problem, it is easy : The frequency of vibrations (fluctuations) with a small amplitude of the ball attached to a weightless string is 1 Hz. I have to find the frequency of small vibrations of this body suspended on the same string near the edge shown in the picture. The distance d of the edge from the suspension point is 1/4...

I'm confused The “height” of the triangular area enclosed by the underneath wire and the one above is the same as the distance traveled in time v: d = vt, also the base of the triangle like that equals to λ (as in picture) so we get 1/2* λ*vt=A Do I understand correctly that λ is the length of the wires? - in which case the bent one has λ as a sum of these "sides",so that each side is...
